Magnetic Separator Toptic

Magnetic separator is a kind of equipment widely used in the industrial field, especially in environmental protection, mining, wood industry, kiln industry, chemistry, food and other industries. The following is an introduction to magnetic separator:

A. Introduction to magnetic separator:

Magnetic Separator

Magnetic separator is a screening device used to remove iron powder from recycled powder particles. It is based on the magnetic difference of different substances in the ore or mixture, and separates magnetic substances from non-magnetic substances through the action of magnetic field. In mining, magnetic separators are mainly used to process magnetic ores such as magnetite, pyrrhotite, roasted ore, ilmenite, etc., and are also used for iron removal of materials such as coal, non-metallic minerals, and building materials.

Magnetic separators are mainly based on the attraction of magnetic fields to magnetic substances. When the ore or mixture to be processed enters the magnetic field area of the magnetic separator, the magnetic substance will be attracted by the magnetic force, move along the direction of the magnetic field, and be collected by the magnetic components of the magnetic separator (such as drums, magnetic plates or magnetic rollers). As these components rotate or move, the magnetic substance is taken out of the magnetic field area to achieve separation from the non-magnetic substance. Non-magnetic materials are not affected by magnetic force, continue to move along the direction of movement of the conveying device, and are discharged from the magnetic field area.

B. Types of magnetic separators

Magnetic separators can be divided into many types according to the strength of the magnetic field, the type of magnetic medium, the working medium and the structural characteristics, such as dry magnetic separators, wet magnetic separators, permanent magnetic separators, electromagnetic magnetic separators, etc. Different types of magnetic separators have different characteristics and application ranges:

1. Dry magnetic separator: suitable for processing dry and large-sized materials, with simple structure and convenient maintenance.

2. Wet magnetic separator: suitable for processing materials with high water content, such as ore pulp, etc., through the action of water flow to make the ore particles loose, which is conducive to the separation of magnetic materials.

3. Permanent magnetic separator: The magnetic poles made of permanent magnetic materials generate a constant magnetic field, and the magnetic field strength is stable and lasting, which is suitable for long-term operation scenarios.

4 Electromagnetic magnetic separator: An adjustable magnetic field is generated by powering on. The magnetic field strength and direction can be changed by adjusting the size and direction of the current. It has strong adaptability and can be used to process a variety of materials.

C. Structure and composition of magnetic separator

Magnetic Separator

Take wet permanent magnetic drum magnetic separator as an example, it is mainly composed of cylinder, roller, brush roller, magnetic system, tank body, transmission part, etc. The cylinder is made of stainless steel plate rolled and welded, and the magnetic system is an open magnetic system, which is installed in the cylinder and exposed full magnet. The motor drives the cylinder, magnetic roller and brush roller to rotate through the reducer or directly with the stepless speed regulation motor. The working area of the tank body is made of stainless steel plate to ensure the corrosion resistance and wear resistance of the equipment.

D. Maintenance and care

Maintenance and care of magnetic separators are essential to extend the service life of equipment and improve production efficiency. Regularly check the appearance of the equipment, cables and connectors, surface cleanliness, and the status of components such as magnetic media to ensure that the equipment is in good operating condition. At the same time, it is also necessary to regularly inspect and maintain the transmission system, bearings and lubrication system of the equipment to ensure the stability and reliability of the equipment.

PS: Magnetic separator is an important industrial equipment with a wide range of applications and significant economic benefits. Through reasonable selection and maintenance, the performance advantages of magnetic separators can be fully utilized to provide strong support for the production and development of enterprises.

Introduction: Magnetic separator is an important mineral processing equipment. Its working principle is mainly based on the difference in the response of different substances in garbage, ore or mixture to the magnetic field. The following is a description of the working principle of magnetic separator:

1. Magnetic field generation and regulation: A strong magnetic field is generated inside the magnetic separator by permanent magnets or electromagnets. Permanent magnet magnetic separators use magnetic poles made of permanent magnetic materials to generate a constant magnetic field. The magnetic field strength is stable and lasting, which is suitable for long-term operation scenarios. Electromagnetic magnetic separators generate adjustable magnetic fields by energizing. The strength and direction of the magnetic field can be changed by adjusting the size and direction of the current to meet the magnetic separation needs of different materials. This flexibility makes electromagnet magnetic separators more adaptable when processing a variety of materials.

2. Ore pretreatment: The ore to be processed first undergoes pretreatment processes such as crushing and grinding to reduce its particle size and increase its surface area. This step is crucial to improving the separation efficiency of magnetic materials, because after the particle size is reduced, the magnetic material is more easily attracted by the magnetic field, thereby achieving more effective separation.

3. Ore enters the magnetic field area: The pre-treated ore enters the magnetic field area of the magnetic separator through a conveying device. The conveying device is usually composed of components such as belts, chains or spirals, which transport the ore evenly into the magnetic field to ensure that the ore is subjected to uniform magnetic force in the magnetic field.

4. Separation of magnetic substances:

a. Under the action of the magnetic field, the magnetic substance will be attracted by the magnetic force and move along the direction of the magnetic field. These magnetic substances are collected by components such as magnetic drums, magnetic plates or magnetic rollers of the magnetic separator. These components are usually made of stainless steel or strong magnetic materials to ensure sufficient magnetic force and wear resistance. As these components rotate or move, the magnetic substances are taken out of the magnetic field area to achieve separation from non-magnetic substances.

b. For some types of magnetic separators, such as disc magnetic separators, the working principle also involves the rotation of the disk and the flow of slurry. The disk is gradually immersed in the slurry under the drive of the transmission device, and the magnetic ore particles are adsorbed to the two sides of the disk. As the magnetic disk rotates, the adsorbed magnetic ore particles are brought to the water supply device, the mixed gangue is washed back to the slurry tank, and the concentrate is discharged into the concentrate tank under the action of the unloading scraper and high-pressure water.

5. Discharge of non-magnetic materials: At the same time, non-magnetic materials are not affected by magnetic force, continue to move along the direction of movement of the conveying device, and are discharged from the magnetic field area. These non-magnetic materials are usually collected and used for other purposes or treated as tailings.

6. Classification and characteristics of magnetic separators: There are many types of magnetic separators, which are usually classified and named according to the strength of the magnetic field, the type of magnetic medium, the working medium and the structural characteristics. Different types of magnetic separators have different characteristics and application ranges. For example:

a. Dry magnetic separators are suitable for processing dry and large-sized materials.

b. Wet magnetic separators are suitable for processing materials with high water content.

c. Permanent magnetic separators have the advantages of simple structure and easy maintenance.

d. Electromagnetic magnetic separators have the advantages of adjustable magnetic field and strong adaptability.

e. New magnetic separators such as superconducting magnetic separators and high gradient magnetic separators provide effective means for the beneficiation of fine-grained and micro-fine-grained weakly magnetic minerals, further promoting the development and application of magnetic separation technology.

PS: The working principle of the magnetic separator is based on the magnetic difference of different substances in the ore or mixture, and the separation of magnetic substances from non-magnetic substances is achieved under the action of the magnetic field.
